Yeah, as basic as it gets. Heat pump is a way off, need to get the house up to scratch thermally first which is probably not far off 10 years away realistically.
@jellybaby because the door is always open so the cat can get to 'his' bed of course.
I'm not sure I'm sold on having individual TRVs though I realise that's the major benefit of that kind of system. Maybe I just need a slightly better dumb thermostat with a weekend programme.
What's the state of play with smart thermostats in 2025? I have an ancient dumb thermostat that needs upgrading, would go full @ectoplasmosis eventually and do EWI, HVAC & heat pump, though for the moment it'll just be the convenience of having the heating come on an hour later at the weekend.
Leaning towards Wiser because of local control, cheap & good integration with HA if I get into that.
Can't tell if theirs has Matter, or if it... matters.
